The Jack-O-Lantern Spectacular, presented by Citizens Bank, returns to Roger Williams Park Zoo nightly from October 6 – November 6. This breathtaking display of thousands of illuminated jack-o-lanterns features over 125 of the gourds carved into veritable works of art playing out this year’s theme “American Treasures.” And of course, Halloween favorites will be back including the dazzling Laughing Tree with its hundreds of illuminated pumpkins and iconic laughing music.
